IMPROVEMENT IN SELF-LUBRIGATING HANGER AND BOX FOR. SHAITING.

TO WHOM IT MAY CONCERN:

Be it known that I, WELLSLY W. CRANE, of the city of Auburn, in Cayuga county, New York, have invented a new and improved mode of Constructing Hangers and Hanger-Boxes or Bearings for Mill Shafting; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making 'a partV of this specification, and to the letters of reference marked thereon.

It is always the design of the mechanic, in putting up shafting in mills, to locate the centre of cach piece in a right line with every other piece forming the same shaft, or to approximate this as nearly as ordinary skill can do it. But the disturbing influences alwaysvpresent in every locality where machinery is in operation, are such as to move the boxes which constitute the support of the shafting o from the common line carrying the line at such points with them. W'henever this occurs some mechanical means inherent in the construction of the hangers and boxes should exist, such as will enable the mechanic to restore the shaft to a right line easily and Without great loss of time. To attain this point is one of the objects of this invention. Another is so to construct the hanger and boxes that when, from any canse, any portion of the line is not exactly on the common parallelism of all the others, the boxes shall readily conform thereto without producing the least cutting or abrasion so common in this kind of machinery. i A third object of this invention is to carry a self-oiling box, to be used with the improvements above mentioned, such that the line may notrequir lubricating in six months or a year, although in common use cvery day.

Now, in order that others may know how to make and use my invention, I will proceed to describe its construction 4and mode of` operation.

Figure l represents my hanger and the upper section of the box,

Figure 2 the lower section of the boxi, and

' Figure 3 the bearing in which the shaft rests.

A A, fig. 1, are the feet of the hanger B B are slots through which pass the supporting bolts for securing the hangers to the'timbers of the ceiling. Pendentfrom these, and forming a part of the hanger, is the socket C. Through this socket, and well tted thereto, is the wrist or arm D, forming a part of the upper section of the shaft-box E. By this arrangement the box is allowed to turn horizontally, and is supported by means of the bolt F, which enters the upper end of the wrist D, and from thence extends up through the cross-bar G, forming a partA of the hanger, having nuts, H and I, one above and the other below it, for the purpose of regu- Eating the altitude of the box E, and holding the same in position. The box E in its .internal arrangements is made in all respects like the lower sectionvshown in Iig. 2. J represents the oil-cup; K and L the trunnion bearings. M and N, iig. 3, are trunnions on the bearings of the shaft-box, and are designed to fit into K and L, Iig. 2, so as to admit a vertical turning motion to the box O, in which the shaft rests. In the box O are two pieces of lamp-wick, I and G, or other fibrous material used to conduct the oil from the chamber J into and around thcbea-rings by capillary attraction. This arrangement provides or furnishes the oil in proper quantities from the cup below. I have said that the upper box was constructed in all respects like the one below. Now when the box O is placed into the oil-receiver E, fig. 2, or lower section of the box E, as described above, and this lower section bolted to the upper by means ofthe bolts R and S, the box and hanger are complete, and the three elements attained with which I set out, that is to say, the bearings of the shaft are made adjustable hori zontally by means of the slots at A Ain the feet of the hanger, and vertically by means of the bolts and nuts H and I. The wrist D attached to and forming a part of the box E, allows the box to adjust itself to any horizontal deflection of the shaft; and the trunnions M and N allow it, the box, to conform to any vertical delle@- tion of the same; and the arrangement of the oil-cup and wick completes the three points.

Having above minutely described the construction and mode of operating my invention, what I claim as new, and wish to secure by Letters Patent, is

1. The adjustable hanger, 'when constructed substantially so-as above described, as to adjust both on the vertical and horizontal planes, as above set forth.

2. The combination of the vertical and horizontal joints above described, when used for the purpose, and constructed in the manner substantially as above specified.

3. In combination with the above joint, I claim the self-lubricating box, when used as and constructed substantially in the manner above speciicd. n WELLSLY W. RANE.
